High-entropy catalytic material electrode and preparation method thereof

The embodiment of the invention discloses a high-entropy catalytic material electrode and a preparation method thereof. The method comprises the following steps: immersing a cleaned first substrate into an original solution containing five or more metal cations; the first substrate and the original solution are transferred into a reaction kettle together for a hydrothermal reaction, high-entropy layered metal hydroxide M (OH) x grows on the surface of the first substrate, and M comprises five or more metal cations; the first substrate with M (OH) x growing on the surface serves as a working electrode, electrochemical activation treatment is conducted on the M (OH) x growing on the surface of the first substrate through cyclic voltammetry, high-entropy layered oxyhydroxide MOOH with the nanosheet morphology is formed on the surface of the first substrate, and the high-entropy catalytic material electrode is obtained. According to the method, the high-entropy catalytic material electrode with stable catalytic p
